In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.
There are three ways to connect your lead acid batteries—parallel, series, and a combination known as series/parallel. We cover each of these battery configurations in greater detail in our Battery Basics tutorial section of the site should you want to delve in a little deeper or reinforce what you already know.
Connecting in parallel is when you combine two or more batteries by linking the POS (+) of the first battery to the POS (+) of the second battery. In the same way the NEG (-) of the first battery is connected to the NEG (-) of the second battery. You would do the same for each battery added to the string.
Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage.
In actual practice, people put lead acid batteries in parallel and cycle them that way frequently. Just look at RV's and boats and off-grid installations. A fuse for each battery would not be a bad idea. If you are charging them all anyway then what does it matter if one discharges into another?
Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged. The power supply is capable of maintaining the fixed float voltage. In practise, I think it's a good idea to put at least a diode in series with each battery just because stuff happens.
Those are lead-acid batteries, unlikely to explode or catch fire. Fuses still recommended though. $endgroup$ – Maple. ... 0 $begingroup$ It is very common to have …

If a large battery bank is needed, we do not recommend that you construct the battery bank out of numerous series/parallel 12V lead acid batteries. The maximum is at around 3 (or 4) paralleled …

Lead-acid batteries that uses recycled lead or tombstone welds to connect cells may not accept or deliver current at the same rate as lead-acid batteries that use 99.99% pure virgin lead or …
Note, when you parallel batteries, you should have a fuse/breaker per string to prevent a short on one battery string from being feed by the other string--this does add wiring/costs to parallel …
